A door opening / closing button 8 for opening / closing is provided.

Further, in the elevator car 3, a card (not shown) operated by a person who leaves the tenant on each floor at the end is read to set the security start of the tenant corresponding to the floor number of the card, or to each tenant. A card reader 9 is provided as an ID discriminating device that sets security end by a card operation by a person who first enters the room and is in security when there is no person in each tenant and monitors entry of intruders during security.

As shown in FIG. 3, the card reader 9 has a reader head 91, a CPU 92, and a ROM 93.
A RAM 94, an interface 95 for inputting and outputting signals, and a bus 96 to which the read head 91 to the interface 95 are connected, and the passing position of the elevator car 3 output from an elevator control panel (not shown). Based on the car position signal a indicating that the elevator car 3 is stopped and the elevator stop signal b when the elevator car 3 is stopped, the security is terminated when the elevator car 3 stops at the floor where the tenant under security is located.

The card reader 9 also turns on the security lights 52 to 54 of the tenant under security and outputs the car call registration prohibition signals c _{2 to} c ₄ of the tenant under security to the elevator control panel. Ban registration of car calls for tenants who are under security.

In addition, the card reader 9 sends intrusion signals i _{2 to} i ₄ to the elevator control panel when an intrusion sensor in the guarded tenant operates or when a landing button of the guarded tenant is pressed. Is output to report the occurrence of intrusion.

The hall calls from the hall call buttons 102 to 104 are also output to the elevator control panel.

The CPU 92, the ROM 83 and the RA
The configuration with M94 sets the start and end of the security of the corresponding tenant based on ID verification, prohibits the elevator control panel from registering the car call of the corresponding tenant while the above tenant is guarding, and It constitutes the control means of the present invention for notifying that an intrusion has occurred when the landing button of the tenant is pressed or when the intrusion sensor in the relevant tenant operates.

Next, the operation of the CPU 92 of the first embodiment constructed as described above will be described with reference to the flow charts of FIGS. Here, for example, when the tenant on the 2nd floor as the Nth floor exits by the last person leaving the room, and when the first person entering the room thereafter enters the room.

First, in step S1, it is determined whether or not the second floor is being guarded, and if there is a person on the second floor who is not guarding, the process proceeds to step S2.

[0020] In step S2, S3, the second floor of the car call registration inhibit signal c ₂ is not outputted to the elevator control panel, that this for the second floor of the car call registration go freedom to the second floor because it is possible it can.

Subsequently, in step S4, it is determined whether the card is operated by the last person who left the tenant on the second to fourth floors to read the card, and which floor of the second to fourth floors the tenant has When there are still people, that is, when the card of each tenant is not operated by the last person leaving the room on the second to fourth floors, the process returns to step S1 and steps S1 to S4 are repeated until the card is read.

In this state, the card is operated by a person who finally leaves the tenant on any of the second to fourth floors,
When the card is read in step S4 above, step S
Go to 5.

In step S5, if the collated result of the ID number of the read card is not OK, the process returns to step S1. On the other hand, the collated result of the ID number is OK and the I
When the D number is, for example, the number of the second floor, the process proceeds to step S6 to set the intrusion monitoring of the intrusion sensor on the second floor to keep the second floor under guard. Then, the process proceeds to step S7 through step S1.

Then, in step S7 shown in FIG. 5, the security light 52 on the second floor is turned on.

Then, in steps S8 and S9, 2
The car call registration prohibition signal c ₂ on the second floor is output to the elevator control panel to prohibit the car call registration on the second floor. This allows
You cannot use the elevator to go upstairs.

Then, in step S10, it is determined whether or not the intrusion sensor installed in the tenant on the second floor operates, and if an intruder enters the tenant on the second floor and the intrusion sensor operates, step S11. Proceed to.

In steps S11 and S12, the intrusion signal i ₂ on the second floor is output to notify the manager. This makes it possible to deal with intruders.

If the intrusion sensor in the tenant on the second floor does not operate in step S10, the process proceeds to step S13. Then, in step S13,
It is determined whether or not the hall call button 102 on the second floor is pressed, and if it is pushed, an intruder enters the tenant on the second floor and the intruder is trying to use the elevator. Therefore, also in this case, as in the case where the intrusion sensor operates, the process proceeds to steps S11 and S12 to output the intrusion signal i ₂ and notify the manager.

If the hall call button on the second floor is not pressed in step S13, there is no intruder on the tenant on the second floor, and the process proceeds to step S14 shown in FIG.

In step S14 of FIG. 6, it is determined whether or not the card is read. If the card is not read, the process returns to step S1. In this case, since the second floor is being guarded, steps S1 to S14 are repeated and the tenant on the second floor is kept guarded.

In the above step S14, when the person on the second floor of the tenant gets in the elevator car 3 to read the card in step S14, that is, 2
When the first tenant of the first floor tenant enters the room, step S1
Go to 5.

In step S15, if the collated result of the ID number of the read card is not OK, the process returns to step S1. On the other hand, the collated result of the ID number is OK and the ID number is, for example, the second floor number. In this case, the process proceeds to step S16, the output of the car call registration prohibition signal c _{2 on} the second floor is stopped, and the security light 52 on the second floor is blinked to notify the end of the security on the second floor.

Then, in step S17, when the first person entering the tenant on the second floor registers the car call for the second floor, the elevator car 3 moves and stops at the second floor. This is detected based on the car position signal a and the elevator stop signal b.

After the elevator car 3 has stopped on the second floor, the security on the second floor is terminated in step S18, and step S18 is completed.
In 19 and S20, turn off the security light 52 on the second floor,
Ends intrusion monitoring by the intrusion sensor on the second floor.

Thereafter, the process returns to step S1 and the above steps S1 to S20 are repeated.

Although the above operation has been described for the second floor with N = 2, the same applies to the third and fourth floors. Three
On the 4th and 4th floors, security lights 53 and 5 will be displayed during security respectively.
4 is turned on, and registration prohibition signals c ₃ and c ₄ are output to the elevator control panel, respectively. If an intrusion occurs during security on the 3rd and 4th floors, the intrusion signal i
₃ and i ₄ are output.

Furthermore, in the first embodiment, the response to the landing button 102 of the tenant is always enabled regardless of whether the tenant is guarded or not. When the landing button 102 of the tenant under security is pressed, the action is due to the intruder, so that it is possible to detect that the intruder has entered, and at the time of a fire or the like, the intruder can get out. This is so that they can escape.

In the first embodiment, as described above,
Set the start and end of the security of the tenant corresponding to the ID number of the read card, prohibit the car call registration of the relevant tenant on the elevator control panel during the security of the relevant tenant, and the landing button of the relevant tenant Since is configured to notify that an intrusion has occurred when is pressed or when the intrusion sensor in the corresponding tenant operates, the intruder can be detected and the intruder can be detected when the tenant is unattended.

The present invention can be carried out according to the following modes. 1) While the car call registration inhibition signal c ₂ to c ₄ are called during i.e. car not output to the elevator control panel registration is permitted, notifies the display or sound that the in the elevator car 3.

2) The security lights 52 to 54 may be shared with a passing light indicating the passing floor of the elevator car 3. Further, the security lights 52 to 54 may be shared with the car position display light 51. Furthermore, the security light may be shared with the car call display light that displays the floor registered at the time of car call registration. When shared, the brightness is changed to distinguish them.

Example 2. In the first embodiment, the card reader is installed in the elevator car, but it can be similarly installed in the elevator hall on the first floor.

Example 3. In the first embodiment, the security light 5
2 is blinked to notify the end of security, but the security light need not be flashed. Further, the car call indicator light may be blinked as a notice of the end of security.

Example 4. As the ID discriminating device, any device such as a card, a numeric keypad, a fingerprint may be used. Also, these may be used in combination. When using the numeric keypad,
The elevator car call button may be used instead of the numeric keypad.
